Surgical Management of Osteoarthritis

The management of pain in arthritis and the use of cyclooxygenase-2 inhibitors: new paradigms and insights

Chronic pain from arthritis has been one of the biggest causes of disability and loss of function in the United States. This is still the case despite many new insights into the pathophysiology of pain, effective treatment approaches, and new safer medications that can be used for long-term use. There are many different types of arthritic problems. New disease- modifying agents that are available for some of these types of arthritic diseases such as rheumatoid arthritis have the potential to have a substantial impact on improvement in the long-term prognosis. Despite this optimistic outlook, pain often is a significant problem and should be treated whenever it becomes a barrier to function.

Patients' expectations of shoulder surgery

Patients' preoperative expectations of shoulder surgery affect both the decision to proceed with surgery and how patients assess outcomes of surgery. Our goals were to identify patients' expectations of shoulder surgery, to develop and test a patient-derived shoulder surgery expectations survey, and to determine the prevalence of major expectations by diagnosis. An initial sample of 409 patients (mean age, 51 +/- 17 years; 58% men) with diverse shoulder diagnoses were asked open-ended questions preoperatively about their expectations of shoulder surgery. Their responses were grouped into 38 categories including the following: pain relief, increasing range of motion, improving the ability to wash and dress, returning to sports, improving the ability to interact and care for others, and for the shoulder to be back to the way it was before shoulder symptoms started. Expectations varied by demographic characteristics, diagnosis, and functional status measured by the L'Insalata Shoulder Rating Questionnaire and the Short Form 36. The most frequently cited categories were then assembled into closed-format questions to form a draft survey. A second sample of 100 patients with diverse shoulder diagnoses completed the draft survey on 2 separate occasions to establish test-retest reliability. Items retained to form the final survey were frequently cited, represented clinically relevant or potentially unrealistic expectations, and had concordance levels of 0.40 to 0.83 measured by the kappa statistic (71% had kappa >or= 0.60). The final 17-item Hospital for Special Surgery Shoulder Surgery Expectations Survey requires less than 5 minutes to complete. This patient-derived, self-administered survey has several possible uses in daily clinical practice, such as providing a way to learn about the patient's perspectives, providing the orthopaedist with a template to guide a formal discussion about realistic and unrealistic goals, and providing a prospective record that can be used jointly by the orthopaedist and patient postoperatively to assess the outcome of surgery.

Clinical benefit of joint distraction in the treatment of severe osteoarthritis of the ankle: proof of concept in an open prospective study and in a randomized controlled study

OBJECTIVE

Osteoarthritis (OA) is a degenerative, disabling joint disease that affects >10% of the adult population. No effective disease-modifying treatment is available. In the present study, we used joint distraction, a relatively new treatment in which mechanical contact between the articular surfaces is avoided while intraarticular intermittent fluid pressure is maintained, to treat patients with severe OA of the ankle.

METHODS

Patients with severe ankle OA (n = 57) who were being considered for joint fusion (arthrodesis) were treated with joint distraction in an open prospective study. In addition, a randomized trial was performed in 17 patients to determine whether joint distraction had a better outcome than debridement. A standardized evaluation protocol (physical examination, assessment of pain, mobility, and functional ability) was used, and changes in radiographic joint space width and subchondral sclerosis were measured. Thirty-eight patients in the open study have been followed up for >1 year, with up to 5 years of followup in 7 of them (mean +/- SD followup 2.8 +/- 0.3 years). Patients in the randomized study have been followed up for 1 year.

RESULTS

Significant clinical benefit was found in three-fourths of the 57 patients in the open prospective study. Most interestingly, the improvement increased over time. Radiographic evaluation showed increased joint space width and decreased subchondral sclerosis. Moreover, joint distraction showed significantly better results than debridement.

CONCLUSION

The clinical benefit of joint distraction in the treatment of severe OA is proof of the concept. Although the followup remains relatively short and effects over time remain unpredictable, our study creates possibilities for the treatment of severe OA in general. Considering the high prevalence of OA and the lack of a cure for it, joint distraction as a treatment of severe OA may have great medical, social, and economic impact.

Joint distraction as an alternative for the treatment of osteoarthritis

Irrespective of underlying mechanisms, the long-term efficacy of joint distraction in the treatment of severe ankle osteoarthritis at young age validates the concept of joint distraction in the treatment of osteoarthritis. Therefore, joint distraction in the case of severe ankle osteoarthritis may be a treatment of choice. This opens the possibility to study joint distraction as a treatment for other joints. Because knee osteoarthritis is much more common, it is a much greater social and economic problem. Beneficial effects of joint distraction in the case of ankle osteoarthritis, and specifically in the treatment of more common forms of osteoarthritis such as severe knee and hip osteoarthritis, may therefore have a great impact, especially in view of the increasing age of our population.

Care of the older adult following hip fracture

Proximal femoral (hip) fractures are the leading cause of hospitalization for injuries among older persons and constitute a serious health problem. Research shows significant functional losses among older persons following surgery for hip fracture related to a wide range of problems. Because of the physiological, emotional, social, and psychological complications inherent in this particular population, a team approach using a holistic model of care is efficacious when attempting to improve functional outcomes and reduce morbidity and mortality.
